Question

A circle has a diameterof 8 feet. what is the approximate area?
A)12.56ft(squared) C)50.24ft(squared)
B)25.12ft(squared) D)200.96ft(squared)

Answer 1

C)50.24ft(squared)

Answer 2

radius is 4
4^2 = 16

16 x 3 = 48

Answer 3

The equation for the area of a circle is \[\pi r^2\]
and the radius of the circle is the diameter/2.
so you have:
\[\pi 4^2 = 50.24ft^2\]

Answer 4

\[\pi = 3.14159...\]
